Nanosecond laser spectrometer for the ultraviolet spectral regime

该提案要求购买一个激光光谱仪，其中包括一个高功率纳秒激光系统作为主要设备，以及其他设备，用于在紫外光谱区对密集的原子和分子气体进行光谱分析。该装置的目的是作为我的波恩工作组的基本设备的一个普遍可用的部分，并应允许扩展几线的研究进行了迄今为止在可见光谱范围到真空紫外光谱制度。提出的激光光谱仪最初将用于实验，目的是在真空-紫外光谱状态下产生光子的玻色-爱因斯坦凝聚物，从而在光谱范围内实现一种新的相干光源，在这种光谱范围内，传统的激光光源由于需要的活性介质的反转，几乎无法使用，甚至根本无法使用。该激光光谱仪还将为致密分子气体“宏观”样品的碰撞诱导激光冷却实验提供基础。可以预见的是，远至紫外光谱区的大调谐范围和所提出的光源的高功率以及光谱仪的良好光谱分辨率将是这些以及未来研究项目成功的关键。

This proposal asks for the purchase of a laser spectrometer consisting of a high-power nanosecond laser system as the main device, along with additional equipment, for the spectroscopy of dense atomic and molecular gases in the ultraviolet spectral regime. The device is intended as a universally usable part of the basic equipment of my Bonn working group, and should allow to extend several lines of research carried out so far in the visible spectral range into the vacuum ultraviolet spectral regime. The proposed laser spectrometer will initially be used in experiments aimed at generating a Bose-Einstein condensate of photons in the vacuum-ultraviolet spectral regime, thus enabling a novel source of coherent light in a spectral range in which conventional laser sources, due to the required inversion of the active medium, are barely or even not available at all. The laser spectrometer will also provide the basis for experiments on collision-induced laser cooling of "macroscopic" samples of dense molecular gases. It is to be expected that the large tuning range far into the ultraviolet spectral regime and the high power of the proposed optical source combined with the good spectral resolution of the spectrometer will be crucial to the success of these as well as future research projects.
